create tablespace XXXXX datafile 'D:\oracle\product\10.2.0\oradata\oral10\xxxxx.dbf' size 100M;
create tablespace misscall datafile 'F:\app\zphome\oradata\orcl\misscall.dbf' size 2048M autoextend on next 50M maxsize unlimited;
--创建用户
create user username identified by password default tablespace voice_yasen;
--用户基本权限
grant connect,resource to voice_yasen;
--如果需要使用IMP倒入数据,最简单方式给他DBA权限
grant dba to voice_yasen;
